I tested this patch set on Hikey960 with below combinations:

- Only applied the kernel patches;
- Only applied the perf tool patches;
- Applied both the kernel and perf tool patches.

All of them can pass the test for `perf record` and `perf report` 
commands, I think this patch series is promised on Armv8 platform with 
small amount of CPUs.

Tested-by: Leo Yan <leo.yan@arm.com>

As you said that there might be a concern for running this patch set on 
a system with big amount of CPUs. Once you think it's ready for merging, 
please share at here.

Thanks,
Leo
